RE: Pedestrian walk button, mid-crossing, Somerville and Washington Street, Union Square
The Pedestrian Signal post at the raised island mid-crossing in Union Square, at Somerville and Washington Street is inaccessible to wheelchair-mobile pedestrians. The pedestrian-activated button is at least seven feet – 84 inches- away from the wheelchair pedestrian’s hand!
Here are the applicable State building codes:
21.10.2 Location: Controls shall be located as close as practicable to the curb cut serving the controlled crossing and shall permit operation from a clear ground space.
21.10.4 Clear ground space: A stable and firm area, complying with 521 CMR 6.5, Forward Reach, or 521 CMR 6.6, Side Reach shall be provided at the controls. Where a parallel approach is provided, controls shall be within ten inches (10″ = 254mm) horizontally of and centered on the clear ground space. Where a forward approach is provided, controls shall abut and be centered on the clear ground space.
Thanks very much for your attention to this safety and accessibility need in Union Square.
